This is on CHIRP next-20250404 on W10.

I am trying to copy&paste in a single memory channel line 3 from another radio into an Alinco DR-735T file line 3. The Alinco file was created by "download from radio", the source of the copy happens to be UV-5R. It fails to populate the column values in the Alinco tab and the left channel number column is now red "!*3" with "list index out of range error".

I did reduce my test to just one line of copy&paste, after the bulk load of ~100 channels failed. Most of them errored out the same way but some magically worked with no obvious indication to why it worked or not. I can provide screenshots, chirp files or CSV exports if needed.

Please advise what I should try next or what other diag logs I can post here.
